Roof leak investigations for homes and businesses in Brill
On older houses, leaks often start at lead work and hidden gutters. Worn lead, tired valley linings and blocked parapet outlets are frequent causes. A central valley gutter on a butterfly roof often turns out to be the source in heavy rain. We check parapets, valleys and flashings from every safe vantage point. Our report shows what we found, with photos. Common reasons to book are damp ceilings under a flat roof and damp patches next to the stack, on the roof space, flat roof details and valleys and parapet gutters.
For a small place like Brill, the inspection is the same as anywhere: we simply plan the journey and access ahead. It is useful to know where the water appears, in what weather, and what you’ve seen outside, plus any earlier repairs. If you have photographs of the water coming in, they help as well.
After the visit, you get a written report with photographs, emailed to you. It sets out the condition of the leaking roof, any defects and our written recommendations.

What you can safely check yourself
During heavy rain, look at the gutters from ground level or a window. Overflowing water can point to a blockage or a sagging run.
Keep a simple record: dates of leaks, photos from the ground and any work done on the roof. Send it with your enquiry and it will help the survey.
Brill roofs and the weather
About 1.9 miles west lies Boarstall Tower, a reminder of how long the area around Brill has been built on. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead. Some villages in Buckinghamshire still have thatched roofs. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. The covering and its details give the first clues when tracing where water is coming from.
Take a building like Brill Church of England School: on a building that size, finding the source of a drip means looking well beyond the stain.

Common roof problems in Brill
Flashings are one of the commonest sources of roof leaks. Where a roof meets a chimney, a wall or a dormer, lead or mortar seals the joint. When lead lifts or splits, or a mortar fillet cracks, rain runs straight in, often well away from where it shows.
Look out for signs like these:
- Water that shows only in certain storms
- Wet patches on loft insulation
- Leaks below a flat extension roof
- Leaks at a dormer or roof window
If you live in an older home near United Reformed Church, water on an older roof tends to find its way in at the lead, the valleys or the chimney.
Questions to ask before booking
- When you will get the report
- What happens after the report arrives
- What they will not be able to tell you
- Whether VAT is added on top
How the survey works
We check the roof from outside and, where it’s relevant and there’s safe access, from inside the loft space too. In the loft, the signs we look for are staining, damp, daylight and sagging. All in, the survey usually takes an hour or two for most homes, though a hard-to-trace leak can take longer. In a hamlet or village like Brill, a postcode doesn’t always lead to the right gate, so a few directions are welcome. After that, the survey runs as it would anywhere.
- We start with your notes and photos of the leak.
- We examine the damp area and the rooms near it.
- In the loft, we follow any signs of water back towards the roof.
- Outside, we check flashings, valleys, chimneys, gutters and flat roof details from each safe vantage point.
- We email a written report showing where the water most likely gets in.
Before we arrive
- If it isn’t your property yet, arrange access through the agent

Common questions in Brill
Is Brill in the area you cover?
Yes. We cover the whole of London and South East England, and Brill is part of that. Just ring 07833 053749 or drop us an email and let us know about the property.
Will you come out to Brill?
Yes, smaller places are covered as well as towns. We work right across London and the South East. Just mention lanes, gates or anything else about the route when booking.
Is it the same as a RICS Level 2 or Level 3 survey?
No. We’re experienced roof surveyors, and our survey covers the roof rather than the whole building. For the rest of the building, a RICS home survey is a separate job.
Will you fix the leak as part of this?
Our job here is to trace the leak and explain it, not to carry out the repair. The report gives any roofer a clear brief.
Do you carry out surveys on Saturdays and Sundays?
Surveys run seven days a week. To find a day that suits you, call 07833 053749 or email us.
Is it a structural engineer’s report?
No. Our survey is not a structural engineer’s report. If we see signs that need an engineer’s opinion, we’ll recommend one.
Do I have to be there for the survey?
If the survey includes the loft or the inside of the building, someone needs to let us in. We’ll talk about access as you book.
How we price roof leak investigations
What a survey costs depends on the time and equipment it needs. That comes down to:
- How tall the building is and how easy the roof is to see
- Which survey package you book
- Any need for thermal images or a drone flight
- The size of the roof
A Basic Survey starts from £150, with VAT included. The Standard Survey starts from £250 and the Premium Survey from £400. You will know the price for your roof before booking.
Getting in touch
When you call or email, these details help:
- Your timetable, like an exchange date
- Pictures from the garden or a window, if you have them
- Anything about access we should know
- Where the property is, with the postcode
To book a survey, ring 07833 053749 or drop us an email with the address and what you’d like to know about the roof. You’ll know the price before anything is booked.

Useful tips for Brill property owners
Some practical points come up on survey after survey. They’re worth knowing whatever the roof:
- Mention earlier attempts to fix the leak
- Let us know if there are tanks or pipes in the loft
- Catch drips in a bucket and protect the floor
- Move stored items away from the hatch
Any roofer you ask to quote can work from the report. They’ll see exactly where the problem is, rather than at the stain.
After a storm, check the roof from the garden and the street. Pieces of slate or tile in the garden mean something has moved. Prompt repairs stop gaps turning into leaks.
